Proportional gain P
The speed of PID adjustment is set by two parameters: proportional
gain and integration time. For fast adjustment, it is necessary to
increase proportional gain and reduce integration time; for slow
adjustment, it is necessary to reduce proportional gain and increase
integration time.
Generally, differential time is no necessary to set

Sampling period T
The larger the sampling period, the slower the response, but the
better the interference signal suppression effect, so it is generally
unnecessary to set it.

Deviation limit
The deviation limit is the ratio of the absolute value of the deviation
between the feedback amount and the given amount of the system.
When the feedback amount is within the deviation limit, the PID
adjustment will not act.

Sleep
threshold
coefficient
If the actual feedback value is greater than the set value, and the
frequency output by the frequency inverter reaches the lower limit
frequency, the frequency inverter will enter the sleep state after the
delay waiting time defined in 03.12 (i.e., running at zero speed); The
value is a percentage of the PID set value.
